摘　　要：城市生态安全的核心问题是生态系统服务的供需平衡。量化分析生态系统供给服务,有助于掌握区域粮食安全和相关产业绿色化水平。运用能值理论定量分析了雄安新区生态系统物质供给服务供需关系和农田生态系统供给负面服务,同时,结合历史数据分析了不同利用类型土地生态系统能值产出的变化。结果表明:1)为提供畜禽产品的其他用地是生态系统供给服务能值最大贡献者,该类型用地贡献了57.9%的能值,其次为提供粮食和蔬菜的耕地,提供的能值占比为30.8%,水域和林地生态系统供给能值比例分别仅占9.9%和1.3%;2)雄安新区生态系统物质供给服务总体处于盈余状态,可实现173.5%的自给率,但随着疏解北京非首都功能的不断发挥,人口不断增加,雄安新区生态系统供给服务自给能力不断减弱;3)农田生态系统正负服务比例逐年减少,生态系统负面服务相对于物质供给服务的增长更快,农业绿色化水平有待提高。The core issue of urban ecological security is the balance between supply and demand of ecosystem services.Quantitative analysis of ecosystem services will help to grasp the level of regional food security and the greening of related industries.The relationship between supply and demand of ecosystem material supply and service and the negative service of farmland ecosystem in Xiong an New Area were quantitatively analyzed by using emergy theory.At the same time,combined with historical data,the changes of emergy output of different land use types were analyzed.The results show that:1)Other land for providing livestock and poultry products is the greatest contributor to the emergy of ecosystem services,and this type of land contributes 57.9%of the emergy,followed by arable land for grain and vegetables,accounting for 30.8%.The proportion of emergy supplied by water and woodland ecosystems is only 9.9%and 1.3%,respectively.2)The overall ecosystem material supply services in Xiong an New Area are in a state of surplus,which can achieve a self-sufficiency rate of 173.5%,but with the continuous development of Beijing s non-capital function,the population continues to increase.Xiong an New Area ecosystem supply service self-sufficiency capacity continues to weaken.3)The proportion of services and disservices of farmland ecosystem has decreased year by year,the growth of ecosystem disservices is faster than that of material supply services,and the level of agricultural greening needs to be improved.
